Turns out, the Domino's delivery driver was supposed to take that $1,300 to the bank after delivering Vegas' order. The driver put the money in a box to keep track of it, and then gave Vegas the wrong box.

Although Vegas posted a picture of the money to his Facebook account with the hashtag #doihavetogiveitback, he did end up returning the money.

"I wanted to keep it, believe me, but I can't. I can't do it."

That good deed certainly paid off: That Domino's location offered Vegas free pizza for the next year.

Crazy thing is -- this has happened before.

CBS reported a similar situation happened in 2013 when McDonald's customers in Tennessee were handed a bag containing cash, which was supposed to go to the bank, instead of their order.

As for the Domino's delivery driver who gave Vegas the box full of cash? KGO-TV reports he's not in any trouble for the mix-up.
